Bringing South Australia one major step closer to a 100% renewable energy grid

Ensuring reliability in a renewable-driven power system

South Australia has a unique opportunity to swiftly decarbonise and transition to full renewable integration with its unparalleled renewable energy sources. Flexible capacity is vital for the state to reach its 100% renewable energy target by 2030, supporting Australia’s net-zero emissions target by 2050.

Wärtsilä’s 250 MW / 250 MWh grid-scale battery at AGL Energy’s Torrens Island Power Station in South Australia is a significant development advancing the nation’s path to decarbonisation. The energy storage system, including both hardware and software, supports the growth of renewables and is the first battery constructed as part of AGL’s targeted 850 MW national battery pipeline.

Flexible capacity with energy storage

In 2018, Wärtsilä signed an engineering, procurement, and construction (EPC) contract for the Barker Inlet Power Station (BIPS) engine power plant located on Torrens Island. The main role of the plant is to ensure reliability in the South Australian power system by providing balancing capacity to manage the variability from renewables. Energy storage can take care of short-duration balancing, while engine power plants can balance variable renewables for a longer duration.

The flexible capacity provided by the Torrens Island battery delivers an efficient means for balancing the supply of energy from renewable sources, thereby supporting the stability and reliability of the grid.

      AGL and Wärtsilä advance frame agreement with first energy storage project on path to grid decarbonisation

      Aug 9, 2021, 08:00 by Wärtsilä Corporation

      The technology group Wärtsilä will supply a battery energy storage system (BESS) to AGL Energy Limited, one of Australia’s leading integrated energy companies. The 250 MW / 250 MWh system will be installed at the Torrens Island in South Australia. It will be AGL’s first grid-scale BESS project, and the second biggest in Australia. When installed, the system will support a broad portfolio of generating assets, both thermal and renewable, and help Australia to decarbonise and transition towards 100% renewable energy future. The order with Wärtsilä was booked in July 2021.

      AGL is an integrated essential service provider with electricity generation capacity of more than 11,000 MW, representing approximately 20 percent of the total generating capacity within Australia’s National Electricity Market (NEM).

      The order of more than 100 MEUR is the first placed under a framework agreement signed between Wärtsilä and AGL in 2020 for the supply of energy storage projects. AGL plans up to 1 GW of grid-scale energy storage across Australia, a country with unparalleled renewable energy resources. The flexible capacity provided by Wärtsilä’s advanced BESS provides an efficient means for balancing the supply of energy from renewable sources, thereby maintaining the stability and reliability of the grid. Energy storage technology will play a key role in the Australian energy sector’s transition from conventional fossil fuels towards cleaner, renewable energy.

      “AGL and Wärtsilä both share a vision to bring cleaner sustainable energy to the market in the most efficient way possible. We are excited to see our grid-scale energy storage plans coming to life, and work with Wärtsilä, a company with a leading position and an impressive track record in energy storage technology, as a project partner,” commented AGL Chief Operating Officer, Markus Brokhof.

      “This is a landmark project, and we are proud to have been selected as the ESS provider. Renewable generation is growing rapidly in South Australia, and the flexibility of our technology and the in-house experience we bring, can together be instrumental in maintaining a reliable and affordable electricity supply for South Australian consumers – both household and business – for years to come,” said Sushil Purohit, President, Wärtsilä Energy.

      The Torrens Island system will be delivered by Wärtsilä on a full engineering, procurement, and construction (EPC) basis, and designed to provide grid-support capabilities to AGL’s asset portfolio. It is expected to become operational in the early part of 2023.

      The Wärtsilä system will operate initially in grid-following mode before switching at a later date to grid-forming mode (virtual synchronous generation--VSG), making it the largest energy storage solution capable of operating in this mode. This will enable very fast response times and will future-proof the Torrens Island facility. The complex solution is supported by Wärtsilä’s advanced GEMS Power Plant Controller and energy management software.

      Wärtsilä has earlier supplied a successful 211 MW power plant for AGL, the Barker Inlet Power Station, also located on Torrens Island. The plant operates with 12 Wärtsilä 50DF multi-fuel engines running on natural gas. The hybrid combination of gas-fuelled combustion engines and energy storage will play an increasingly important role in Australia’s energy future.
